Dynamic Vapor Sorption (DVS) is a gravimetric sorption technique that simultaneously measures the amount and kinetics of a vapor being absorbed by a sample. This is done by varying the vapor partial pressure surrounding the sample in a controlled environment and measuring the resulting change in mass. Water vapor is the most commonly used solvent.

Dynamic vapor sorption (DVS) enables the gravimetric measurement of the sorption isotherms of water and organic vapors (e.g. short-chain alcohols) at constant total pressure by varying the partial pressure of the adsorptive in a constant N2 stream. The sorption temperature can be varied between 5 °C and 60 °C and the relative humidity between 0 % and 95 %.
- partial pressure: 0 < p/p0 < 0.95
- Temperature range: 5 – 60°C
- Accuracy of balance: 1 µg
